OlIL-SEPARATOR.

5pecification of Letters Patent.

Patented Jan. t, 1913.

To all whom it may concern:

Be it known that we, FREDERICK M. S reams and Louis PESHA, citizens of the United States, residing at Marine City, in the county of St. Clair, State of Michigan, have invented a new and useful Oilbeparator, of which the following is a specification.

This invention relates to oil separators, and has for its objectto provide a simple and eflicient device of this character adapted to be interposed in a water line for separating the oil from the water passing therethrough.

rVith the foregoing and other objects in view which 'will be apparent as the invention is better understood, this invention resides in the novel construction and combination of parts hereinafter described and particularly pointed out in the appended claims, reference being had to the accompanying drawings wherein the invention is illustrated, and wherein,

Figure 1 is an-elevation of the oil separator. Fig. 2 is a vertical central section thereof. Fig. 3 is an enlarged sectional view taken on the line 33 of Fig. 2, parts being broken away.

Referring in detail to .the drawings, wherein similar reference characters have been employed to designate corresponding,

parts, the numeral 4 designates a cylindri cal casing, which has the ends thereof open, and which has caps 5 screw-threaded on the ends thereof. These caps 5 have the inner concentric bosses 6, which bosses are provided with sockets, and a rod 7 extends axially through the casing 4 and has the ends thereof engaged in the sockets of the caps or ends 5.

An inlet pipe 8 is attached to one side of the casing 4 intermediate its ends and communicates through the casing, and an outlet pipe 9 passes through the opposite side of the casing and has the inner end thereof depending in a close relation to the corresponding side of the casing and terminating short of the lower cap 5, as designated by the numeral 10.

A diaphragm 11 is arranged on the rod 7 within the casing directly above the inlet, or at a point slightly above the inlet, and a second diaphragm 11 is arranged on the rod 7 below the inlet and at a point slightly above the lower end of the outlet pipe 9, or at a point between the .inlet and outlet provided for the casing, this gage having its ends communicating with the ends of.

the casing.

The upper diaphragm 11 forms an oil collecting or accumulating chamber 17 above same and a circulating chamber below same, this circulating chamber being partitioned off by the diaphragm 11 into the upper portion 18 and a lower portion 19. The inlet communicates with the upper portion 18 of the circulating chamber and the outlet communicates with the lower por-- tion 19 of the circulating chamber, so that the water in passing through the separator from the inlet to the outlet is required to pass through the lower foraminous or porous diaphragm 11'.

In use, the separator is interposed in the water line, such as the water line for feeding a boiler, and the water passes into the casing 4 through the pipe 8, and is delivered therefrom through the discharge pipe 9. The water in entering the casing 4 below the diaphragm 11 will cause the oil and other lighter liquid to rise through the upper diaphragm 11 into the chamber 17, and as the diaphragm 11 separates the chamber 17 from the circulating chamber, the oil and other liquids contained in the chamber 17 will be prevented from circulating, thereby preventing the mixture of the oil with the outflowing water after the oil has ascended through the upper diaphragm. The water in passing through the lower diaphragm 11 will be strained so as to exclude foreign objects from the outflowing water, and the lower diaphragm also serves to divide the circulating chamber into the upper and lower portions communicating respectively with the inlet and outlet, so that the circulation of the water between the inlet and outlet is modified in order to insure the effective operation of the separator. The oil may be permitted to flow from the chamber 17 by opening the pet cock 15, the said pet cock being arranged at various vertical points permitting the oil to be removed from the various vertical points.

This separator may be employed for various purposes, such as removing oil from water supplied to the boilers of steam vessels, mills and the like, or where feed water is taken from the discharge of a condenser. This device serves to effectively separate the oil from the water flowing through the device, and permits the oil to be completely saparated from the water circulating from the inlet to the outlet, so that the accumulated or collected oil will not be disturbed by the circulation of the water and may remain in quietude. The various pet cocks also permit the oil of various densities to be removed, the oils of various densities forming into stratas within the chamber 17, as will be readily understood. Theoil caught within the chamber 17 may be utilized for various purposes if desired, or may be discarded as waste.

This device may be readily taken apart for repair or cleansing by removing the caps 5 from the ends of the casing 4, in which event, the rod 7 and the diaphragms may be removed.

This separator consists of but comparatively few parts, and may be constructed at a small cost, and in its use is both convenient and eflicien't.

It is understood that the number of diaphragms may be multiplied as is deemed -necessary or essential, and this device is otherwise susceptible of alterations or deviations in its details, such as changes in size, proportions, materials and the like, within the scope of the appended claims without departing from the spirit of the invention.

Having described the invent-ion, what is claimed as new is 1. An oil separator adapted to be interposed in a water line and embodying a casing having an inlet at an intermediate point and a lower outlet, the inlet and outlet being designed for the attachment of the sections of the piping of a water line so that the water flows through the casing, and a toraminous diaphragm fitting in the casing above the inlet and forming an oil collecting chamber above the same in order that any oil mixed with the Water flowing through the casing will rise through the diaphragm and into the oil collecting chamber, the oil being collected in the said chamber and being removable therefrom.

2. An oil separator adapted to be interposed in water lines embodying a casing having a lower inlet at an intermedlate point and an outlet, a foraminous diaphragm fitting in the casing, above the inlet and forming an oil collecting chamber and circulating chamber above and below same, respectively, and a foraininous diaphragm fitting in the casing between the inlet and outlet.

3. An oil separator adapted to be interposed in water lines, embodying a cylindrical casing having an inlet in one side at an intermediate point, an outlet pipe passing through the other side of the casing and depending to the lower end along the same side, foraminous diaphragms fitting in the casing at points directly above the inlet and slightly above the lowenend of the said pipe, and the casing being provided with an oil outlet above the upper diaphragm.

4. An oil separator embodying a cylindri--- cal casing having an inlet in one side, caps engaged on the ends of the casing and having inner sockets, an outlet pipe passing through another side of the casing and depending to the lower end along the same side, a rod having its ends fitting in the sockets, diaphragms on the rod at points slightly above the inlet and slightly above the lower end of the said pipe, each diaphragm comprising a pair of perforated disks and an interposed screen, and a plurality of pet cocks attached to the casing above the upper diaphragm at differential vertical points.

In testimony that we claim the foregoing as our own, we have hereto affixed our signatures in the presence of two witnesses.
